| 中文摘要: |
| 依据1：5万水系沉积物测量资料，对雄梅地区水系沉积物地球化学特征进行了初步分析。通过对元素分布、元素相关性、单元素异常、组合异常等特征的研究表明，该区Pb、Zn、Au、W、Sn、Bi等元素具有一定的成矿潜力，结合野外异常查证工作，推断大多数异常受岩浆岩和构造作用控制，区内与酸性岩体有关且强度较高、元素组合较好的异常区有利于成矿。依据水系沉积物综合异常的圈定，结合区内成矿地质构造背景，进一步优选出桑心日钨锡多金属矿、查江铅锌多金属矿2个远景区，并在后续的野外工作中得到了相应的验证。 |
| 英文摘要: |
| Based on 1：50000 survey data of drainage sediments, the geochemical characteristics of the Xiongmei area, Tibet were preliminarily analyzed. The study of element distribution, element correlation, single-element anomalies and combined-element anomalies shows that Pb, Zn, Au, Wu, Sn, Bi and other elements exhibit a certain mineralization potential in this area. Combined with field verification, it is inferred that most of the anomalies are controlled by magmatic rocks and structures, and the abnormal areas with high strength and good combination of elements are favorable for mineralization. Based on the delineation of the comprehensive anomalies of drainage sediments, combined with the metallogenic geological setting in the area, we have further optimized 2 prospective areas; one is the Sanxinri tungsten tin polymetallic deposit and the other is the Chajiang lead-zinc polymetallic deposit, which have been verified in the subsequent field work. |
